The mathematical model of the operating mechanism for turbochargers

Diplomová práca je zameraná na vytvorenie matematického modelu kinematiky ovládacieho mechanizmu turbodúchadla DAVNT (Double-Axle Variable Nozzle Turbine) pre nastavovanie polohy lopatiek. Práca obsahuje krátky prehľad preplňovania a typov turbodúchadiel. Hlavná časť obsahuje matematický model, ktorý skúma správanie mechanizmu pri uvažovaní opotrebenia medzi jednotlivými členmi. Súčasťou je aj hodnotenie zmeny jednotlivých častí v uzloch mechanizmu spôsobených opotrebením a ich vplyv na mechanizmus vzhľadom k dôležitých parametrov charakterizujúcich mechanizmus. Hodnotenie je doplnené optimalizáciou parametrov. Záverečná časť obsahuje výpočet interných statických síl a hodnotenie umiestnenia aktuátora s ohľadom na zaťaženie mechanizmu.The Diploma Thesis is focused to create the mathematical model of operating kinematic model for turbocharger DAVNT (Double Axle Variable Nozzle Turbine) for setting the position of vanes. The work contains a brief overview of supercharge and types of turbochargers. The main part contains a mathematical model which examines the behavior of the mechanism with considering of wear among the parts. It also includes assessment of changing in various parts of the nodes caused by mechanism wear and their influence on the mechanism due to important parameters which characterizes the mechanism. The evaluation is completed by optimizing the parameters. The final section contains the static calculation of internal forces and assessment of actuator position relative to mechanism load.

Mobile apps that support physical activities and the potential of these applications in physical education at school

The current trend in using digital technology to support physical activity (PA) is unstoppable at that time. The growing number of mobile device users maximises the possibility of the better utilisation of these devices for the support of physical activities. The objective of this paper is to create an insight into the use of mobile technologies in the physical education process and to establish the underlying considerations of their use. In the paper we generally discuss the utilisation of digital technologies in education and we focus in more detail on physical education as a subject and we examine the potential of mobile apps designed to support PA. A sub-objective is to define the possible risks associated with the use of these technologies. The paper also includes a survey research directed at a target group. The survey research focuses on the current status of how mobile technologies have spread over and how they are used in PE classes and the realisation of PA. Having studied literary resources we pursue the fundamental description of the technologies used in mobile apps, as well as the availability, functions and basic categorisation of these mobile apps. In the practical part of the paper we publish the initial results of our research plan, the introductory part of which we effected using survey research directed at a target group, that being primary and secondary school teachers and students from selected regions in the Czech Republic. The results of our work confirm the current tendency to use mobile technologies in connection with the realisation of physical activities. The high level of mobile devices used by the target group and the practical experience associated with the use of mobile apps to support PA indicate the potential for introducing mobile apps in lessons. Nonetheless, there are currently no appropriate recommendations, such as peer-reviewed application databases, that can be used in the physical education process. Mobile apps are a relatively new tool for interventions associated with health and physical activity and few academic works have been published in both Czech and foreign literature in regards to the impacts of mobile app use in this field. Where physical education classes are concerned, mobile apps represent low-cost and broadly used tools that need to be subjected to further expert investigation, mainly in relation to the enormous number of these mobile apps and the possible risks associated with their use

Assessing the FACTS: A Mnemonic for Teaching and Learning the Rapid Assessment of Rigor in Qualitative Research Studies

Teaching and learning research appraisal strategies is a challenge in undergraduate education and for practitioners alike. The appraisal of rigor in qualitative research papers is particularly complex and sophisticated work for many undergraduate research students and practitioners who want to develop their critical reading skills. The mnemonic strategy (The FACTS) explained in this paper is one pedagogical strategy for establishing a simplified approach to teaching and learning the appraisal of rigor in qualitative research. While not a comprehensive tool, the FACTS are a useful introduction to the complex challenge of qualitative research appraisal

Thermal summation model and instar determination of all developmental stages of necrophagous beetle,<i>Sciodrepoides watsoni</i>(Spence) (Coleoptera: Leiodidae: Cholevinae)

Necrophagous beetles are underrepresented in forensic entomology studies despite their undeniable utility for the field. In the present article, information is presented regarding the developmental biology and instar determination ofSciodrepoides watsoni(Spence, 1813), a very common species occurring across the Holarctic region. Wild collected beetles were kept in climate chambers at constant temperature (12, 15, 18, 21 and 28 °C) and their development was regularly documented. Parameters of thermal summation models and standard errors were calculated for each developmental stage. These models may be used for an estimation of post-mortem interval in legal investigations after further validation on local populations ofS. watsoni. An additional methodology is introduced for future studies of size-based characteristics, addressing instar identification bias. The methodology provided estimations (mean, standard error and standard deviation) ofS. watsonilarval head capsule width for preliminary larval instar determination. The methodology may be used with other morphological features to improve instar determination accuracy.</jats:p

Prime periods of periodical P-additive functions

I. Korec [Ko] introduced the following definition of a P-additive function. DEFINITION. A function F: N→R is said to be Pythagorean-additive (P-additive, for short) if for all x,y,z∈Nx2 = y2+z2 ⇒ F(x) = F(y)+F(z). The aim of this paper is to determine all prime numbers that are periods of P-additive functions. The main result is the following theorem. THEOREM. Let the prime number p be a period of a P-additive function. Then p∈{2,3,5,13}
